摘要： An optical communication module which uses a single optical fiber to enable bidirectional communication or multiplexing communication is provided. The optical communication module includes a platform configured to have a through-hole therein which vertically passes through the platform; an optical receiver configured to be provided on the platform and include a light-receiving element; an optical transmitter configured to be provided on the platform and include a light-emitting element; and an optical filter configured to be provided on one surface of the platform to correspond to the through-hole, transmit light from the light-emitting element to an optical line, and transmit light input through the optical line to the light-receiving element, where one of the light-receiving element and the light-emitting element is provided on one surface of the platform on an opposite side of the optical line with the optical filter interposed therebetween, and the other is provided on the other surface of the platform to correspond to the through-hole. Accordingly, it is possible to reduce the manufacturing cost, minimize the optical or electrical crosstalk, and maximize the optical coupling efficiency.

摘要： A method of manufacturing a stacked semiconductor package using an improved technique of forming a through via in order to enable 3-dimensional vertical interconnection of stacked packages is provided. The method includes forming a seed layer required for forming a via core on a bottom surface of a wafer, forming at least one via hole vertically through the wafer, forming a via core in the via hole, insulating the via hole from the via core, and removing the seed layer from the bottom surface of the wafer. The stacked semiconductor package is suitable for high-speed signal transmission.

摘要： A wavelength division multiplexing passive optical network system is provided. A central office generates a multi-mode light having a mode interval equal to a period interval of a multiplexing filter of the remote node and the multi-mode light is used to control a wavelength of an uplink transmission optical signal of the optical network unit. A remote node multiplexes the multi-mode light with the multiplexing filter to transmit the multiplexed multi-mode light to the optical network unit and demultiplexes the uplink transmission optical signal to transmit the demultiplexed uplink transmission optical signal to the central office. An the optical network unit generates the uplink transmission optical signal by modulating a data signal with a Fabry-Perot laser which uses the multiplexed multi-mode light as an injection optical source. Accordingly, it is possible to control a wavelength of a transmitter of the optical network unit by using the injection optical source generated by the central office.
